Description

technical field [0001] The present invention relates to a generation device, in particular to a graphene generation device using an electrochemical exfoliation method to generate graphene. Background technique [0002] Graphene is a single-layer atomic thick carbon material with sp 2 Hybridization forms bonds with three adjacent atoms and extends into a honeycomb-like two-dimensional structure. Graphene is known for its good carrier mobility. Because of its excellent electrical properties, chemical stability, good thermal conductivity and high permeability, it has been widely used in semiconductors, mobile phones, and tablets. , touch panels or solar cells and other fields of popular materials. [0003] Generally, graphene is produced by methods such as mechanical exfoliation, epitaxial growth, chemical vapor deposition (CVD), and chemical exfoliation. Among them, although the mechanical exfoliation method and the epitaxial growth method can generate graphene with better ...
